Ocean Optics has expanded its Elite Series of high-performance modular spectrometers with the introduction of the Ventana line of high-throughput spectrometers. Ventana spectrometers combine an optical bench configuration with very high collection efficiency and a high-efficiency volume phase holographic (VPH) grating to provide high throughput and sensitivity for low light level applications. Three pre-configured Ventana spectrometers are available: 532-nm and 785-nm excitation wavelength Raman models, and a visible to near-infrared model for general-purpose fluorescence applications.

The 785-nm Ventana system has a spectral range of 250 to 2,000 cm^-1 and resolution of 10 cm^-1. The 532-nm version covers 35 to 4,300 cm^-1 with 20 cm^-1 resolution. The VIS-NIR Ventana spectrometer is configured for fluorescence measurements from 430 to 1,100 nm with a resolution of 4.0 nm (FWHM). Also, the 785-nm Raman Ventana spectrometer can be configured with an integrated laser with free space collection optics for high throughput. Complete Raman sampling systems—including laser, probe, and software—are available.
